Circus roses were first bred in 1956 in the United States by Herbert Swim. They were introduced later that year to the US market by Armstrong Nursery. Herbert Swim was a famous rose breeder who bred roses for blooms that would hold up to the hot summer sun. He is credited with raising several varieties of roses over his career. The rose Circus was created by crossing the Floribunda rose Pinocchio with the hybrid tea Fandango rose. The result is this gorgeous yellow rose that produces great reddish edges. The Floribunda rose Circus will produce blooms that are somewhat smaller than you might be used to on a floribunda, only reaching diameters of about 2.75 inches across. The petals will be extremely full however with well over 40 petals per bloom. The plant itself will grow to a typical size with heights reaching up to about 4 feet tall and equally as much in width, at full maturity. For all its fancy colouring, this variety of rose has only a subtle tea fragrance.
